Recomedations on 4K TV for use with PS4

As the title says I'm just after a 4k TV for use with my PS4 pro. I'm looking for around the size of 43" since it's only for my bedroom. As well as playing games I will be watching movies on Amazon or 4k YouTube vids etc. the main use will be gaming though so I'm after something that is great for gaming like a low input lag and atleast a 60hz refresh rate so far I have only found one TV which is within budget.It is the Samsung UE40MU6120 40" Smart 4K , what are your thoughts on this? I'm still looking around for other Tv's but it would be nice to know what everyone else thinks
